| Chamber structure | 1. Adopting a segmented and openable structure, stainless steel inner liner structure, and ceramic roller drive 2. Each section of the upper furnace body is equipped with 2 electric cylinders, which can be independently and automatically opened for maintenance 3. The electric cylinder has a self-locking function in place, ensuring safe operation after opening; At the same time, it has the function of tightening in place, improving the sealing effect of the sealing surface of the furnace body 4. After the furnace is opened, it is easy to maintain the interior of the furnace and add safety support to ensure the safety of maintenance operations 5. Glass is easy to clean and can be quickly cleaned after being broken in the cavity 6. Add lifting lugs on the top of the furnace to facilitate later lifting and maintenance 7. Arrange transmission rollers at furnace entrance and exit |

| Effective width | 640mm, glass suspended width 615mm |
| Drive roller rod | High precision ceramic rollers. The contact between the transmission shaft and the cavity is protected by a sleeve to prevent the furnace body from stretching due to heat, affecting the transmission shaft, and providing insulation while avoiding the entry of external dust. |
| Maximum Load | 20Kg/piece |
| Transmission mode | Roller continuous transmission. When conveying, the glass edge only contacts 0.75-1.25cm, and the rest does not touch the roller rod; The glass conveying is stable, and the roller table can limit the glass conveying without deviation; The roller limit will not damage the glass corners |
| speed range | 200-2000mm/min, typical process belt speed 1540mm/min |
| transmission accuracy | From import to export, product deviation within ± 3mm |
| driving system | The transmission control adopts a servo drive motor, which is controlled through a servo controller and the speed is continuously adjustable |
| Conveyor structure | The roller drive device is driven by a servo motor through a sprocket and chain, which drives the driving shaft and drives each roller rod through gears between the driving shaft and each roller rod, thereby driving the transmission of products |
| photoelectric control | Optoelectronics at entrance and exit |
|
|||
| Atmosphere control system | Including intake air pipes, exhaust system | ||
| Air pipes: The range of the auxiliary flow meter is 10-95L/min, while the range of the other flow meters is 20-190L/min | |||
| A | Entrance gas curtain | Prevent external air from entering the furnace | |
| B | Rubber discharge gas intake | Used for supplementing normal fresh air in the heating section | |
| C | Venturi Exhaust | Air inlet is used for auxiliary exhaust, and variable diameter venturi is used for chimney to control air displacement by adjusting extraction pressure | |
| D | Firing gas intake | Used to control the airflow direction in the furnace and prevent rubber pollution during product firing in high-temperature areas | |
| E | Exit gas curtain | Prevent external air from entering the furnace | |
| Exhaust system | One exhaust chimney is installed in front of the temperature zone, and an exhaust hood is installed above the inlet section of the furnace | ||
| Stop button. | Entrance and exit plates are equipped with a stop button. After pressing it, the transmission stops running |
| Alarm indication | Overtemperature, temperature deviation, servo alarm, thermocouple broken sound and light alarm, discharge alarm |
| Temperature measurement | Each control and detection point is measured independently by K type thermocouple |
| Control instrument | Use of intelligent temperature controller, with PID parameter auto tuning, high temperature upper limit alarm, thermocouple failure and other protective alarm functions. |
| Heating control | The heating part is supplied by several AC contactors in groups to reduce the instantaneous current impact of the equipment on the power grid. |
| Control mode | Solid-state relay zero crossing triggering mode |
| Over temperature Alarm | When over temperature occurred in some zones, over temperature alarm system in corresponding zones immediately send audible and visual alarm signal and meanwhile the heating of this zone is cut off, the buzzer sounds alarm |
| Computer Control System | DCS (distributed control system) control system is adopted |
| Lower single loop intelligent instrument control, upper industrial control computer monitoring | |
| Friendly man-machine interface, multiple program storage, convenient for users to edit and call | |
